Borussia Dortmund has never actually won every Bundesliga match. They are known for playing only to create professional players so that they can sell their great players to several clubs that need their players. Borussia Dortmund is already famous for business like this.
I don't know whether to be happy or sad at the same time, but this is true, it's famous like that. But yes, at least they are still trying their best, especially in the Bundesliga, the top domestic league, where in fact, for starters, they can go even further next season. Even though they played badly, they lost to a lower club with a fairly big score, this is really a massacre. which is sad for Dortmund. Because in fact, many people have high hopes for this club after they qualify for the UCL final, which is truly prestigious.
This is exactly different with Leverkusen, in which, although they have been clearly as the winner of Bundesliga, but so far, they are still struggling their best to perform the best, too. As like the previous match, Leverkusen could beat Bochum incredibly by scoring 5 goals and without any conceded goal. Maybe because Bochum was also very unlucky, because they got a red card at a fairly early time. so this gives Leverkusen a higher chance of winning.
